Question

Heat capacity of a substance is infinite. It means

• A. heat is given out
• B. heat is taken in
• C. no change in temperature whether heat is taken in or given out
• D. All of the above

Answer 1

The correct option is

A

no change in temperature whether heat is taken in or given out

As we know,

$Q=ms\Delta T$

$nows=\frac{1}{0}$

$\frac{Q\times 0}{1}=\Delta T$

$\Delta T=0$

Infinite thermal capacity implies that there would be practically no change in temperature whether heat is taken in or given out.
